Patented Oct. 18, 1938 N ST TE- f m-men This invention reiates ,to vwaterproof surface covering strips, and particularly pertains to composition roofing elements formedinto strips with ornamental designs imprinted-upon the weather exposed surfaces. a ,Heretofore ornamental prepared asphalt roofing sheets or slabs have been manufactured from a a foundation felt orfabric saturated and coated with bituminous compositions,=and..then surfaced with embedded in thecoating as granular mineral material partially roofing manufacture, Thereafter. various designs maybe effected-by further embedding cerwith the color of the granular material. Or grooves of slight depth-may first be depressed in I the asphaltcoating, and then-the granular Inaterial is appliedandpartially embedded in those The depth of the groove is accentuated by ,reasonof the granular However, in: carrying out 'these the granular surfacing'and'without weakening the strips. The roofing is preferably composed of a homogeneous mixture substantial thickness.

For a full and more detailed understanding of the invention reference is made to the accompanying drawing, in which:

Figures 1 and 2 are perspective views of one embodiment of the invention;

Figures 3 and 4 are perspective views of a modified form of the invention;

Figure 5 is a perspective viewof another embodiment of the invention;

Figure 6 is a top plan view of Figurel; and, are perspective views of still Figures 7 arid 8 further embodiments.

Referring to the drawing, numeral 2 designates a roofing sheet which is composed of a mass of bituminous material, such as asphalt, and a filling thoroughly intermixed and molded into form. A suitable filling may comprise comexftent', I I density {in thesresultingmassi" -To prepare a suitable mixture, the bituminous tain areas of the granular material into theicoat i j ing to expose areas of asphalt coating to contrast is. conventional in sequently be subdivided into; suitable lengths.

one design (Figures; 1 and 2) inla y be. the 2 I 7 form ofj'complementa 'y. concave depressions 3 andconvex'ridges 4 alternately disposed andextending transversely of'the strip. Preferably the strip is of tapered configuration with the thicker.

portion 5 comprising'the weather edge of the strip, and the transverse depressions and ridges formed only on the weather. exposed face. If it is desired to cover'the weather exposed face'of the strip withg'ranular material, one marginal edge 6 is preferably left uncoated in order that it may contactwith the under marginal surface of an adjacent strip whenoverlapped in courses. In imprinting the depressions, some of the bituminous material will be caused to flow or roll over the edge of the strip in the form of artistic 40 waves 1 These waves may vary in extent,

terminating short of the reverse side of the strip or, it desired, extending flush with the reverse side of the strip as shownat 8 in Figure 3. Also they may be'formedon the edges of the ridges as'at 9 in Figure the depressions. I I

'I'heembodiment in Figure 5 shows a different design formed on the weather exposed side of 4 aswell as on the edges of the roofing or siding element. The strip has one edge thickened and a series of raised portions illl are set off at intervals by depressions ii. In forming the depressions and raised portions'a portion ofthe material is squeezed ,to project beyond the base edge of the strip in order to pro- A an,

vide a continuous marginal lip l2 and I3. Numeral i2 designates that portion of themarginai lip which projects from the raised portion, and I3 designates that portion which projects from the depressed portions II.

In the embodiment in Figure "7 the same general structure results in the strip as in that embodiment in Figure 5, but the raised portions I are of different contour, being somewhat convex on the outer surface. Formation of vthe recesses H and the raised portion 10 squeeze the material to provide a continuous lip, including the portions I2 which project from the raised por tions and I3 which project from the recessed portions H The raised portions in any of the embodiments may be merely coated with a waterproofing coating or may have'granular material partially embedded ina waterproofing coating or in the composition material from which the roofing or siding sheet is made.

In Figure 8 a siding or roofingsheet of the same' composition as the other embodiments is shown. This, however, is. molded or ;embossed to efiect a difierentjdesig'ni. Sheet I4 is provided with a series of terraced or stepped portions l5 extending longitudinally hithe stripl4; 7 ,These 'or siding structure. y i I While I have shown several preferred .embodi terraced or steppedJportionsuIS may be further set off into 'raisedportions I! by providing a series of cross 'groovesor lines ilfiifthe roofing or siding i s1provided,jwith granular surfacing material. The lines "may be etlectedby leaving these portionsqnncovered, thereby causing the composition material to beexposed at these areas to contrast with the other portions which are covered with the granular material. Asa result the roofing or siding effects certain novel designs by virtue of the stepped portion and also the'exposed'surface is inade to simulate individual shingles by the transverse divisions IS. The top edge of the shingle is preferably of, re-

duced thickness in order that it may underlap,

and a series' of these shingles or strips may be laid in overlapping courses tov cover a roofing ments of my invention, and-detailed descriptions thereof, it will be understood that the invention is not limited thereby but that varloim changes may be made therein without departing from the spirit of the invention.

I claim:

1. A covering strip comprising a homogeneous mass'of adherent plastic material having a plane undersurface, a series of elongated raised portions and depressions formed on the weather exposed face to provide an ornamental design, some of said depressions being extended to merge with the butt edgeof the strip,and-a marginal projection extending along the butt edge of the strip and conforming to the surface contour of the raised portions and those depressions which merge with the buttedge oi the strip.

2. A covering strip comprising a homogeneous mass of adherent plastic material having a plane undersurface, a series of elongated raised portions formed on; the weather exposed face to provide an ornamental design, all of said raised portions" and depressions being extended to merge with the buttedge of-th'e strip, and a marginal projectionextendirig along the butt edge of the strip and conforming to the surface contour of the raised portions and depressions.

3. A coverin'g'strip comprising a homogeneous mass of adherentpiastic' material having aplane undersurface, aseries of elongated raised portions and depressions'formed on-the weather exposed face to provideanornamental design, one,

of said depressionsbeing extended tom'ergewith Q the butt edge of the strip, and a marginal pro- .iection extending along the butt edge of the strip and, conforming to the'surf'a ce contour of the thebutt edge of the strip,and granular coating material applied to the raised portions.
